glutShowOverlay(3GLUT)		     GLUT		glutShowOverlay(3GLUT)

NAME
       glutShowOverlay,	 glutHideOverlay  -  shows or hides the	overlay	of the
       current window

SYNTAX
       void glutShowOverlay(void);
       void glutHideOverlay(void);

DESCRIPTION
       glutShowOverlay shows the overlay of the	current	window;	 glutHideOver-
       lay hides the overlay. The effect of showing or hiding an overlay takes
       place  immediately. Note	that glutShowOverlay will not actually display
       the overlay unless the window is	also shown (and	even  a	 shown	window
       may be obscured by other	windows, thereby obscuring the overlay). It is
       typically  faster  and less resource intensive to use these routines to
       control the display status of an	overlay	as opposed to removing and re-
       establishing the	overlay.

SEE ALSO
       glutEstablishOverlay, glutShowWindow
